Abstract: This work deals with the decentralised supervised control of active suspension using neural networks. Firstly, a non-linear control law is synthesised via the backstepping control design approach by using a non linear half-car model. In order to improve the dynamic performances of the closed loop system, a neural network is used to supervise the developed control law. To demonstrate the effectiveness of the proposed control strategy, several simulations are performed on the non-linear system. The obtained results show that the performances are improved by the decentralised supervised controller.
